I just went through the re-installation of SDK 3.7.0-3 on Mac OS X and came across few things that I would like to highlight in this post. It may be helpful for someone else.

The installation is performed on El Capitan: 10.11.6, the WICED SDK is downloaded from here: WICED Wi-Fi Documents & Downloads select a *.7z file, those are for Mac OS X.

The steps are:

Run the instance of WICED Wi-Fi Eclipse CDT. If Eclipse is not installed yet: please use this one here: WICED-SDK-2.4.1 IDE & SDK [Mac OS X Package Installer] There is only one release of the Mac OS X Package installer so you have to start with this version even though the SDK is not the latest one!

When Eclipse is up and running, do File->Import->Existing Project Into Workspace

Under "Select root directory" select the decompressed *.7z SDK that you just downloaded above.
